Your question is not clear? Do you want to add your textbox values to your combobox as items?

You can do it in two ways:
1. Either you can alter your datasource and rebind the DropDownList.
2. Insert the items in DropDownList in TerxtChanged event of your TextBox(AutoPostBack property should be true for textbox to fire server side event). Try this:

C#

drpList.Items.Insert(0, new ListItem(TextBox1.Text.Trim(), TextBox1.Text.Trim()));

Use

C#

//Code here to populate DropDownList
DropDownListID.Items.Insert(0, new ListItem("text", "value")
///
///  0 is the index at which you want to insert the text. Text means the text
///  which is shown to the user and value is a unique value (enum or a number) 
///  which can be used in the code-behind to uniquely identify a dropdown item.
